Peak AI TOPS: 123 TOPS
Notes: RDNA 3 adds 192 AI Accelerators, two per compute unit, that execute WMMA matrix instructions for FP16, BF16, INT8 and INT4. AMD rates the card at 123 TFLOPS FP16 matrix, 123 INT8 TOPS and 245 INT4 TOPS, against 61.3 TFLOPS of peak FP32. There is no FP8 or TF32 path, and FP64 runs at a reduced rate.
